5485C HIGH-TEMPERATURE VELOCITY TRANSDUCER
Installa on Manual
2-PIN CONNECTOR VERSION
(requires ma ng Model 4850-XXXX cable)
FIXED ARMORED CABLE VERSION
1180
DOC # M8109 • REV K (Feb 2015)
OVERVIEW
The Metrix 5485C High-Temperature Veloc-
ity Sensor is suitable for use in temperatures
up to 375 C. It is designed for gas turbines
and other machinery with high surface tem-
peratures where a velocity signal is desired.
The sensor's moving-coil design requires no
external power as it self-generates a signal
propor onal to vibra on velocity.
FEATURES
• Self genera ng, no power required
• Stainless Steel Housing
• Zero fric on - infi nite analog resolu on
APPLICATIONS
• Large industrial gas turbines
• Furnace fan monitoring
HAZARDOUS AREAS
UL intrinsically safe for Class 1, Div. 1, Grps
(A-D); Non-incendive for Class 1, Div. 2,
Grps. (A-D). CSA intrinsically safe for: Class
1, Div. 1, Grps (A-D); ATEX/IECEx intrinsically
safe for: EEx ia IIC T1-T6 Ga.

- Page 2 INSTALLATION The sensi ve axis of the transducer can be oriented in any direc on. To ensure clean response to high frequency vibra ons, the transducer must be securely mounted to a fl at machined surface using four #6 (or 3mm) socket head screws. If a bracket is required, it should be of rigid construc on to prevent spurious mechanical resonances in the pass band.
